Referring to fig. 1, in one embodiment, the invention discloses an electronic cigarette chip with humidity detection, which is characterized in that:
the chip comprises a sensing and processing circuit of an air flow signal, a sensing and processing circuit of a humidity signal, power tube driving logic and a memory, wherein,
the sensing and processing circuit of the air current signal is used for providing a first air current signal for the power tube driving logic;
the sensing and processing circuit of the humidity signal is used for providing a second humidity signal for the power tube driving logic;
and the power tube driving logic is used for retrieving a first threshold value and a second threshold value from the memory, comparing the first airflow signal with the first threshold value to output a first control signal, comparing the second humidity signal with the second threshold value to output a second control signal, outputting a heating control signal at least according to the first control signal and the second control signal, and further controlling a heating circuit outside the chip to adjust the heating power of the smoke cartridge according to the heating control signal.
It can be understood that when the user uses the electronic cigarette, the smoking action involves the humidity environment of the oral cavity, so the operation logic of the electronic cigarette chip involves sensing and processing the humidity, but the ambient humidity itself is also an interference factor, so the embodiment further considers sensing and processing the airflow. And the chip operation can be controlled more specifically by the relevant threshold value in the memory in the chip in advance. Therefore, the electronic cigarette chip can manage the energy management of the electronic cigarette chip through the power tube driving logic, thereby reducing the waste of electric energy of a smoke cartridge and a battery, and being beneficial to maintaining the service life of the heating element. In other words, under the background that the electronic cigarette has started to be popular, the invention can improve the energy-saving level of the electronic cigarette chip and reduce the environmental hazard as much as possible.
In one embodiment of the present invention,
the chip also includes sensing and processing circuitry for temperature signals, wherein,
the sensing and processing circuit of the temperature signal is used for detecting whether the electronic cigarette enters the oral cavity or not and providing a third control signal for the power tube driving logic based on the detection result;
the power tube driving logic is used for outputting the heating control signal according to the third control signal on the basis of the first control signal and the second control signal.
It should be noted that, because the large environment and the small environment inside and outside the oral cavity of the human body are different, which relates to the difference of the temperature, especially, in the process that the electronic cigarette instantly enters and exits the oral cavity, there is a jump in the temperature, and therefore, the present embodiment detects whether the electronic cigarette enters the oral cavity or not through the temperature. The prior art does not have the technology, but the embodiment can further control heating through temperature, and the electronic cigarette is more intelligent, better in human-computer interaction and also capable of ensuring the effects of energy conservation and environmental protection.
In one embodiment of the present invention,
and the power tube driving logic carries out logic OR operation according to the first control signal and the second control signal and outputs a heating control signal according to an operation result.
In one embodiment of the present invention,
and the power tube driving logic carries out logic OR operation according to the second control signal and the third control signal and outputs an intermediate control signal according to an operation result.
For the above embodiment, the power tube driving logic may further perform a logic operation on the first control signal and the intermediate control signal based on the intermediate control signal.
In one embodiment of the present invention,
the memory records the temperature and humidity signals every time.
The scheme for recording the historical values can be further used for judging whether the inside and outside temperature and humidity of the current inside and outside environment of the human oral cavity are relatively close to each other. In order to reduce the erroneous operation when at least one of the temperature and the humidity is relatively close or the same, for example, in some geographical areas with a relatively special temperature and humidity in summer, the power tube driving logic may perform a logical and operation according to the second control signal and the third control signal, and output an intermediate control signal according to the operation result.
In one embodiment of the present invention,
the chip also includes light sensing and processing circuitry.
And the light sensing and processing circuit is used for detecting whether the electronic cigarette is instantly changed by light and outputting a fourth control signal.
It can be understood that the above embodiments can further detect whether the electronic cigarette enters the oral cavity through light changes besides humidity and temperature.
In one embodiment of the present invention,
and any one of the sensing and processing circuits of the airflow signal, the humidity signal, the temperature signal and the light is further used for detecting whether the airflow, the humidity, the temperature and the light generate interval jumping or not.
For this embodiment, the behavior of the intervals of the inlet and the outlet of the electronic cigarette is even periodic, so that the intervals of some users are periodic. However, more appears to be intermittent behavior in a general sense, since it is rather aperiodic for the user. This behavior results in large-small airflow and intermittent jumps in humidity, temperature, and light.
Therefore, the invention can record the historical value through the memory and judge whether the jump occurs through the power tube driving logic, and the detection capability of whether the electronic cigarette enters the oral cavity or not is improved through any sensing and processing circuit or any combination thereof by taking the jump as a characteristic. And based thereon, each sensing and processing circuit outputs a corresponding logically true or false control signal, such as a first control signal, a second control signal, a third control signal, and a fourth control signal, when it detects that the e-cigarette enters or leaves the mouth through the aforementioned jump. And, in order to reduce the misoperation, carry on the logical AND operation to two control signals among them at least.
In one embodiment of the present invention,
when the first control signal is true, the heating control signal is true regardless of whether the second control signal is true, and the heating power to the cartridge is increased at the current output power level of the heating circuit.
In one embodiment of the present invention,
when the second control signal is true, the heating control signal is true regardless of whether the first control signal is true, and the heating power to the cartridge is increased at the current output power level of the heating circuit.
In one embodiment of the present invention,
when the first control signal is false and the second control signal is also false, the heating control signal is false, and the heating power to the cartridge is reduced at the current output power level of the heating circuit.
In one embodiment of the present invention,
the chip is MCU or other chips.

the microphone capacitor and key processing circuit is connected with the capacitor input pin CAP and the switch input pin SW and is used for receiving a capacitor touch signal and a traditional switch signal and further providing an output signal to the power tube driving logic and the display control circuit;
